OF INNERSOLES.

Patented June 29, 1909.

Although my invention in some of its fea.

tures is capable of a wide application, it rearticularly to the manufacture of reinforcer leather innersoles known in the market as Gem innersoles, such as are referred to in my patents dated Feb. 3', i906, Nos. 812,383, and 812,384. Before my invention set forth in said patents, the time-honored method of making Gem innersoles was toccment a strip of reinforcing fabric to the leather foundation constituting the innersole by means of rubber cement (naphtha solutions of rubber), which necessitated the coating of the leather with cement and then the coating of the canvas with.

cement,-permitting both of them to dry, and

then pounding them together by special machines. V

My-present invention has for its object the manufacture ofsuch Gem innersoles with ordinary plain uncoated canvas or duck, cemented directly to the inncrsolc, while avoiding the aforesaid cumbersome, expensive, objectionable and delaying features of the old method, attending the use of rubber cement.

One of the leading features of my present invent-ion resides in the discovery of the fact that simply by first soaking the fabric with water, it becomes possible to "use regular cement it. 6., cement which does not contain naphtha or other volatileingredient as in the it has heretofore been considered impracticableand in fact impossible to make a Gem innersole (i. 0., a canvas-reinforced innersole) by directly ccmenting the canvas to its foundation by ordinary cement, because the cement would ienetrate the canvas, thereby losing most of its efficiency, requiring an undue amountof cement, and when hardened so stiffening the innersole that it could not be used. I have found that by first rendering the fabric "liable and cement repellent by immersing 1t in liquid, preferably hot water or moist steam, or otherwise swelling the fibers, the fabric may then be applied directly to the leather of the innersole by means of freshly applied ordil'iary cement, and that the-result is a superior inncrsolc. the hot water to the cement-receiving surface fills and swells the fibers of the duck with the water, so that they cannot absorb the ccment. This prevents the cement from strils cement to the surface, so that it is not ab sorbed and does not penetrate into the canvas and hence does not stiffen the canvas, but is all left effective on the surface for cementing purposes. \"Jithout' this preliminary filling and swelling of the fibers of the duck or canvas with nmisturc, such as water, the application of ordinary cement would permit the latter tosaturate the fibers, and such saturating of the fibers of the canvas .with cement wouid upon. the subsequent hardening of the cement separate and weaken the fibers, so as to make the fabric incapable of withstanding the stitching strain, would stiffen the fabricto the injury of the imiersole,.an(l would render the exposed surface of the canvas when on the inncrsolc, unsightly and more or less sticky, besides wasting the expensive cement and ing it practically impossible to operate the machines at speed, because of the presence of so much cement. My method, however, obviates all these disadvantages, so that it apply the canvas to the leather by means of fresh non-volatile cement. I The cement takes hold of the wet canvas sufficiently to and all remains ellicient at the surface for adhesion to the leather, so that only a comparatively thin layer of cement is required, insuiiicient to stiffen the innersole appreciably.

to include any suitable resinous, glucy, or gutiiawerrha cement, which is non-v0 atile in the sense of not having a naphtha solvent or equivalent highly volatile solvent such as characterizes the so-callcd rubber cements.

In the preferred form of my new method, I not only cniploythe fabric in an uncoated stat e,saturated with moisture or at least having; its cement-receiving surface swelled and choked or rendered substantially impervious The application of gul'nming up the n'iaehines, thereby rcndcr-- becomes practicable and advantageous to adhere thereto but cannot follow the fiber-,

By the term ordinary cement-s I mean.

ing in or through the fabric and restricts the sure the canvas and leather.

l manner of fresh cement directly to the fabcement basin andsupported tirely eliminate this latter feature and ob' tain the required pliability of the innersole simply by avoiding the stifi'ening of the canvas by a complete and penetrative coating, depositing instead thereof an exceedingly restricted amount of cement in fine ridges or small segregated heaps accurately controlled or regulated in amount to the predetermined quantity just necessary to unite underpres- This not only renders amply sufiicient an amount of eement which, if spread all over the fabric as a regular coatin would be entirely inadequate and too thin, and if applied in the usual ric when dry, would be absorbs hereby and practically disappear, but it obviates the objectionable, deleterious and delaying effects of the watervrhen applied on the external surface of the coating (as in my patented method), and entirely eliminates the subsequent dry heating. My apparatus besides including means for producing this prelimi nary filling of the fibers with moisture for the cement-repellent purposes above ex lained, includes special means for further writing the amount of cement coating on the surface of the canvas and for delivering the freshly tank 14 is providedthrough a pipe 30 tapped cemented canvas properly to the operator.

In the drawings, in which I have shown a preferred embodiment of the machine, Figure 1 shows the apparatus in side elevation, parts being broken away for clearness of illustration; Fig. 2 is a view thereof in front elevation, parts being broken away for the same reason; Fig. 3 is a top plan view of the scraper knife; Figs. 4 and 5 show in section and )lan the fabric containing the definitely rcgul be pressed directly upon the innersole body; Fig. 6 is a large sectional detail showing the p )sition of the scraper with reference to the pilot and cement basin; Fig. 7 is a horizontal sectional view showing the front part of the plan; Fig. 8 is a lan view 0 the scraper showing its general outline; and Fig. 9 is a view in rear elevation of the removable pilot. In many respects 1 consider my invention as broadly new, but in order to present my invention clearly I will describe the same in connection with the specific details of the preferred form or" my apparatus.

ated lines of wet cement in readiness to;

arts in top Mounted on, a frame 1 is a cement tank 2 maintained warm by hot waterin its walls its-indicated at 3 and provided with an out let 4 controlled by any suitable, means as.

by a hand-operated valve 5 for delivering cement in proper proportions and. desired amounts to a basin 6, herein shown as providedwith a steam-jacketed bottom 7 and.

central portion 8. The basin 6 provides an excessive layer of the hot cement on-the duck. The duck or canvas 0 is drawn in" .strip form from any suitable supply, herein shown as a roll 9 removably mounted'0n' standards 10, whence the duck is led over a guide roll 11 to an immersing ,roll'. .1 2"

removably lournaled'at 13 in awater tank 14. From this tank the duck is led through a tension device 15, so'const'ructed that it scrapes oil the'surplus water and also provides a little drag on the strip 'of duck, which then passes to a guide roll 16 on the front end of the cement basin. From the guide roll 16 the duck strip is led downwardly underneath and about a pilot of fabric-guiding device 17, which is removably supported in'position to depend into the cement. After the fabric has thus been coated it is led against the scraping edge of a scraper or knife 18 and thence up over a delivery wheel 19 to thework table 20, said wheel being preferably provided with a driving pulley 21 for feeding purposes.

Steam is admitted by a valve .22, being delivered by a branch 23 controlled by a valve 24 to the jacket of the cement supply tank 2 and then by a branch 25 controlled by a valve 26 to the steam jacket 7 of the cement basin 6, at 27, and then by a third branch 28 controlled by a valve 29 to the water basin 14. A proper supply of water for the water at 31 into the jacket 3 of the supply tank 2 so as to deliver the overflow therefrom to the water tank. A suitable vent pipe 32 is prefilow pipe 33 from the steam j acketed portion of the'cement basin 6 is provided, controlled by a valve 34 and emptying into an outlet pipe 35 which leadsofi-to a drain or to a return system at 36. An overflow pipe 37 connects thereinto from the water tank. To drain the steam jacketed portion of the machine 1 provide a peteock 38. other parts which are engaged by the. fabric are made adjustable and removable for convenience in getting the fabric strip into place, the roll12 being mounted in bearings 39 pivoted at 40 and normally held in roll supporting position by springs 41.

The pilot or fabric guiding tool or device 7 is shown best in Figs. 2, 6 and 9, where it The rolls and adapted to rest on the edges of the cement tank, being held in place by projecting collars 43 adjlusted and tightened by set screws 44, said pi 0t 17 being removable by a handle 45. Projecting from the upper edge of the pilot 17 are springs 46 held in place by a block 47 to bear against the o posite sides of the fabric (see Figs. 2 and 6? so as to hold said edges pressed tightly against the scraper 18 for the purpose oflpreventing the cement from being drawn up by the edges of the fabric in undue amounts. The inlet supporting means, herein shown as the roll 16, and the delivery means, herein shown as the scraper blade 18, are so disposed as to compel the fabric stripto hug the pilot so closely and tightly that cement is applied to that side only of the fabric from Which the surplus is scraped off by the scraping device, and notwithstanding that the entire fabric goes down into the cement no cement Whatever is permitted to get on the opposite side of the fabric. To enable the fabric to be readily put in place the pilot is made removable and preferably the scraper blade or knife is also made removable. The scraper 18 is shown best in Figs. 3, 2, 6, 7 and 8, having end portions 48 to be engaged by overhanging spring clips 49, and a handle 50. The scraper blade is cut out at 51' to fit the under portions 42 of the adjacent pilot and is serrated or notched at 52 to aid in controlling definitely the amount of cement which is left thereby in ridges or longitudinal heaps or stripes on the strip of fabric being cemented. The notches control the size or extent of the ridges of cement and the teeth act to scrape off all the cement between said ridges so that the fabric 0 is coated with ridges or slender lines or heaps c of cement as shown in Figs. 4 and 5. It will be obvious that the desired spots, lines or other segregated heaps or small nar row deposits of cement may be delivered to the fabric by a wide variety of mechanism, all within the spirit and scope of my invention. The serrated knifelike plate or blade is simple and effective and enables me to accomplish another very important feature already incidentally mentioned. The spreading of linear layers of cement leaves the fabric pliable and greatly facilitates the folding of the canvas over the lip portions or stitchreceiving ribs of the iunersole. It helps the trimming also, by not requiring the knives to pass through a continuous layer of cement or cementitious coating (which has been the case with previous methods, including my patented invention). Each line or stripe provides a definite surplus of cement which constitutes the special means of attaching the canvas to the leather with the extreme minimum of cement which characterizes my invention, and without any danger of leaving the innersole stiff. For it will readily be understood that the raised linear body or heap of cement flattens and spreads instantly un der the pounding action of the Gem innersole machine, spreading over the adjoining uncoated surface or section of the fabric, and at the same time increasing its hold or base of adhesion on the latter. Aside from thepoint of economy and general adaptability of this feature of my invention, I have found this lateral spreading of the cement from the linear heaps or stripes a most simple method of providingenough but not too much c oat ing to accomplish the desired purpose. This is important, for by this means, in connection with the soaking or steaming step of my process, I canaccomplish the very best re sults with loss cement than would provide the very thinnest coating over the whole surface of the fabric, whereas with said thin coating there would not be enough cement at any one place to effect any adhesion to the leather.

At the rear of the scra )er is a catch plate and strainer 53 removab y supported by its hook shaped end 54 on the edge of the basin 6, for catchin surplus cement, lint, threads, etc., dislodgedfrom the fabric by the scraper, said part 53 having slits 55 in its lower part for the exam 0 of the cement therethrouglr back into t in basin. The centra portion of the steam jacket is cut away at 6 for the free flow of cement therethrough to the front part of the basin into contact with the'canvas. The scraper is removed very readily simply by pressing back one or the other of the s rings 49 and lifting the blade 18 upward y by its handle 50; If it is desired to put a new piece of canvas in place, the clam ping devices 43 are swung around out of engagement with the pilot or guiding blade 17, which isihen lifted out of the cement basin by means of its handle 45, and placed on top of the web of canvas. The blade 17 is then pushed downwardly into the cement basin, carrying the 'anvas with it, and when in place is fastened by the clan'iping devices or olders 43 as before. The tension device 15 consists of a scraper blade 57 whose downturned ends are held by thumb screws 58, see Fig. 2, and a Ushaped rod 59 secured to said blade as shown clearly in Figs. 1 and 2. To hold the canvas taut and prevent its running ahead by momentum when suddenly pulled by the operator, a. drag in the form of a bent plate 60 pivoted at (")1 is provided to rest on the web as it passes over the guide pulley 11. The heated transverse portion or table 8 is provided for maintaining the cement extra fluid at the front portion of the basin and as it comes up on the canvas, and also for maintaining the scra er warm so as not to smear the cement but eave th'e ridges'clean and neat.

In. use the operator atthe table 20 pulls the canvas alon step by ste as required for the individua innersoles w ich are to be the la se of considerable time.

T4 sufiicient-ly to render the fibers of its cement-receiving surface practically impervious to cement, or in other words thewater fills and swells the cotton, thereby rendering ittemporarily non-absorbent so that the fiber'syare cement-renellent and hence when the canvas reaches the cement tank it is capable af'receiving only a minimum top coatmg instead of'being saturated by the penc trative cement: The water tempers the fabric so that it is pliable and soft and at the same time fills the "pores thereof just sulficiently to prevent the cement from striking through the fabric and yet to permit the cement to adhere to the surface of the fabric. By having the Water hot or by using steam, and by having the cement hot, the cement is maintained in a state of fluidity and tractabilitywhich ermits the fabric to be cemented immovab y to the leather solefeven after Not only does t e presence of the moisture in the fabric prevent the penetration of the cement beyond the surface, but it cooperates with the scraper in restricting the cement to the desired nnnimum necessary tor the purpose.

Preferably the fabric is not permitted to come 11! contact with a not medium alter leavlng the cement, or in other words i have purposely designed my apparatus to maintain the canvas-handlin arts of the mas P chine warm until the cement nas been applied, whereby the cement is applied under conditions which produce in it the greatest fluidity and best condltlons for surface coating Without Waste of the cement.

Heretofore it has been considered desirable, 1f not indeed necessary, to keep the surface which is to receive cement as nearly dry as possible, as it has been supposed that it Would render the cementing process defective, and accordingly, the canvas has either been applied substantially dry to the innersole (as with rubber cement) or has been coated before being immersed or steamed (as in my patent No. 812,383, February 13, 1906), or has been first coated and then subsequently moistened slightly on the uncoated side 'orback of the canvas only (as in my patent No. 853,326, May 14, 1907), whereas y my new process herein contained the ocment-receiving side of the canvas is moistened just before receiving the cement, thereby interposing this barrier of moisture "for preventing the hot cement penetrating or striking too far into the fabric, and com elling said cement to remain on the sur ace Where it is required for use. to limit my invention to any particular cement. A gutta percha cement or other non volatile, strongl T adhesive, quick-setting cement is prefera le, and the cements'mentioned in my aforesaid patents or in my patent No. 855,868, datedJune 4, 1907, ma be used, or any other suitable cement ca ab e of.

sticking to leather and canvas. T e temperature of the water in the Water tank 14 is regulated by the admission of more or less steam through the valve 29, While the condition of the Water surrounding the supply tank 2 is noted by observing the air or steam escaping from the pi e 32. The location of the outlet ipes in t efjacket of the supply tank and t e cement basin insures that normally they are heated by hot water, thereby maintaining a gentle, even heat, which I have found preferable for use with the kinds of cement mentioned.

As already intimated, and as will be more apparent from the claims, I do not intend to restrict myself to the particular mechanism and specific details of the apparatus and process herein set forth at length, but have described the same herein'minutely for the better comprehension of the invention. The Wetting of the fabric previous to its receiving the cement revents the soaking in of the cement, and a-so the segregating of the cement to separate heaps or stripes further conduces to this end.

The chief object of my,inven'tion is to prevent the stiffening of the fabric and to maintain the same extremely pliable when being shaped to conform to the inner-sole in the usual gemmin process. The cement is restricted entirely to one side of the fabric, leaving the other side clean, non-stifiened, and slack, and is restricted. as nearly as possible to the extreme outside surface of the fabric, as, a superficial coating, and hence is I do not intend entirely distinct and difierent from the man- 4 ufacture of multiply fabrics, such as ,tarred roofing paper, 'lazed hlotters, pasted paper articles such as cxes and photo-mounts, etc.

My invention is not to be confounded with the graining of wood or ornamental finishing of rubber cloth such as gossamer, in both of which instances the painted or coated board .or cloth receives athin coating of coloring matter which is then lined or figured by a suitable scraping tonlso as to produce the desired contrasting color effect or other figured surface according to the ornamentation desired, (as in Videto, No. 371,155, patented October i, 1887). My invention has no connection with ornamentation, and does not employ the paint-like fluid or coating reqlillired for said ornamenting purposes, but t e apparatus is totally diiferent, conslstlng of means for controlling a quantity of sticky cement so as tovinsure the heaping up on the fabric of a predetermined or certain heavy coating in segregated masses or stripes of definite quantity exactly suflicient to secure the fabric strongly to the leather of the innersole.

My apparatus is not a scratching or grainingmechanism to apply a figure to a coated fabric or surface, but is an apparatus for controlling the amount of the cement by the depth of the scra er grooves. Said grooves govern the heapec up stripes as to shape and amount of cement, in accordance with the kind of cement, kind of fabric, and kind of leather surface which receives the fabric, with that predetermined nicety which will secure the most nearly perfect uniform adhesion of the fabric to the leather when vertical pressure upon the fabric causes the heaps or stripes of cement to be flattened. or spread out laterally over substantially the entire surface of the leather and fabric. The rows or stripes of heaped up cement are deposited hot, when the cement would naturally have the greatest penetrating power, and the coment being quick setting remain in heaps until nearly set or in an almost or quite cold condition, whereupon the spread ng pressure is applied, which operates to flatten out the cement over the intervening substantially 'uncoated areas when the cement has reached a comparatively non-penetrating condition. Thus in this manner, taken in connection with the preliminary swelling of the fibers with moisture, I secure the maximum elliciency of the cement for oining the two surfaces together instead of losing a great part of said efficiency because of the disappcar-" ance of a large proportion of the cement in the cloth by absorption.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
